Could have been two Levan Horns stacked, OR an Emnerald and a Levan horn stacked.

When I was in Miami 1989-1996, when they re-opened the 1235 washington Av location known as DECOS, 1235, PARAGON, and THE ARTIST FORMERLY KNOWN AS PRINCE, they originally had TWO MASSIVE stacks, firing out into the room, with an emertald on top a levan horn, two Puissance cabinets and two Double D horns, with mid horns and tweeters as well.

They also had two stacks with a single levan, single puissance, and one DD horn, with mid horn, and bi radial tweeters and even though these can produce high SPL, size wise, they were small in comparison to the stacks that were doubled up.

Has anyone pics from the puissance?
What is it double 15" horn loaded?

Puissance was a double 15in horn loaded LF cabinet. This type of horn loading is also called a " bent horn ", or a C horn. It is a sealed rear chamber, front horn loaded cabinet that looks like a scoop except you can't see the woofer cones.

This cabinet produces an unbelievable and SOLID kick with good extension and VERY high output. Hard to beat!
